Configuring openvpn server and client

one doubt –---------------> in the 3rd line why its showing "tun-ipv6" im using ip4 only .

server LAN address 192.168.116.254/24
client lan address 192.168.114.254/24
tunnel 10.0.8.0/24

anything else????

johnpoz

So in your client you have

auth SHA256

Where is auth statement in your server config??
At a loss to how that could go missing??? Unless your manually messing with the .conf file?

@jerryxLinuX:

No. You want to upgrade your pfSense.

jerryxLinuX

ok i try in other network were pfsense is updated. and let you know.

jerryxLinuX

While trying from another two network its working fine , in vpn status i got status " up and bytes sent and received are changing only in bytes:
but while trying to ping from one network to other it fails.

jerryxLinuX

sorry for the wrong update , client can access the server but server is not responding to client .
what might be the issue .
while trying ping from client its success ,
while trying ping from server to client it fails

johnpoz

firewall on client is quite often blocking…

jerryxLinuX

Still same problem , server cant able to access client
checked firewall i have made rules same as server on client.
any configuration for firewall rules do you have

jerryxLinuX

Firewall/Rules
Tab OpenVPN
Create rule: pass, any, any, any

i gave all but still now no luck

doktornotor

Which part of "firewall on client" was confusing? Most importantly - there are firewall logs, use them!!!

jerryxLinuX

how to check firewall log?
status–>systemlogs-->firewall tab. is it so : i have found oly tcp are blocked in my client Ip varies not the server IP is blocked in there.

in server config
what to mention in advanced option
push "route server.o subnet" ; route client.o subnet;
is this the correct way ? why we are doing this?
in my case
eg. push "route"192.168.114.0 255.255.255.0";route 192.168.140.0 255.255.255.0

johnpoz

Dude.. The CLIENT firewall… Why would that be in logs on pfsense?

What OS is your client?

jerryxLinuX

the client firewall is also pfsense . i am trying to communicate b/w two pfsense.
or i mistook your question

johnpoz

So where did you state that? What IP are you trying to ping? An IP on the network in your site to site connection? Or the pfsense client vpn IP, or its lan or its wan?? What?

Did you create a peer to peer or a remote access on the server pfsense? What networks do you have at each site??

edit: Dude while I don't normally mind PMs with questions, etc.. Post your stuff in this thread… And what networks are on each side and what is the tunnel network.. Who exactly are you trying to ping.. These are basic questions that we need to know if you want any sort of help..

so my server ip is : 192.168.114.254
my client ip is : 192.168.140.254

i can ping from client(140.254) to server(114.254) , but not from server(114.254) to client(140.254)

any other info needed , sorry for giving less details

johnpoz

please just post up a gui shot of your client config and server config.. Your not editing the .conf manually are you?

What do you have in your outbound nat on the client? On the server? What is the routing table on pfsense of the client look like and on the server side.. On the client you should be putting in what networks are remote..

so your not natting anything through your vpn interfaces.. Fine since your just all local networks.. But you don't have anything in your remote or local networks You don't normally have to push routes.. Unless your doing something specific odd..

Where are you routing tables from pfsense?

jerryxLinuX

Routing table means? how to get that?
